LTE vs. Wimax comparison

[alqasim]

for 10 MHz bandwidth: 1024 subcarriers , subcarrier spacing: WiMAX 11 kHz, LTE 15 kHz ... which system is more immune to ISI ?

Is there any more info is required ?

Thats an unreasonable question.

ISI happens when the previous symbol is very late due to multipath and comes when the next symbol is already receiving.
Subcarrier spacing related to symbol duration, but from ISI the guard interval protect us. And it is not related in general to symbol duration but to operation range of the system and energy reasons.
You should post the guard intervals of these systems. Which is longer - that system is more immune to ISI.

Some days ago I was reading a blog which was about LTE(Long Term Evolution) vs Wimax technology. It was interesting to read it and I definately want to share it..

Both WIMAX and LTE were 4G technologies which aim to improve the limitations of 3G technology or third generation technology. WIMAX and LTE were officially accepted to be IMT-2000* or (International Mobile Telecommunications of year 2000). WIMAX gains more competitive advantage than LTE because 802.16e was already achieved the standard for a period of time, while the standard of LTE still be in process.
